## Overview

LazyLLM is a low-code framework for composing, running, and iteratively improving multi-agent LLM applications. The main workflow is developer-built modules and flows, served to users through a web interface; applications can use model backends, agents/tools, and RAG over document collections. The README also describes data-feedback-driven optimization and one-click deployment across infrastructure. RAG, model, and orchestration paths are supported by the tree and README examples; sampled source excerpts are limited, so edges reflect documented behavior rather than uninspected call chains.
